Is it my Wi-Fi, or is the site down? Where does the connection break? Why does Safari distrust this certificate? Is my public IP really mine, or am I behind my carrier's NAT? Which devices are on my Wi-Fi? Did my computer really wake up? Radien answers these questions on your iPhone or iPad, directly on the device, and honest about what it can and can't see. No ads, no trackers, no analytics, no accounts. Nothing you type is sent to a server we operate. WHAT'S INSIDE • Radien Checkup: one run checks your Wi-Fi, router, internet, DNS and websites, and tells you what is wrong. • Network Scanner: see the devices on your Wi-Fi or wired network, how each one answered, and their names. With iOS 27, see each device's MAC address and maker, and what changed since your last scan. Nothing leaves your network. • Wake on LAN: wake a computer, NAS, server or gaming PC on your network, or away from home through your own VPN, then watch it wake. Radien says whether it woke and what to check if it did not. Siri, Shortcuts and widgets can wake it too. • Ping: latency, jitter and packet loss to any host, with a live chart and a plain-language verdict. • Multi Ping: compare up to four hosts side by side, at once. Saved groups load a whole comparison in one tap. • Traceroute: every hop between you and a destination, with reverse-DNS names, the network that holds each address, and a read of where delay or loss truly begins. • DNS Lookup & Reverse DNS: query A, AAAA, MX, TXT, NS and more against the system resolver or Google, Cloudflare and Quad9. Enter an IP for a reverse PTR lookup and the network that holds it. • Port Scanner: which TCP ports are open, closed or filtered (usually a firewall), never a fake vulnerability claim. • TLS Inspector: read a site's TLS/SSL certificate chain, protocol versions and cipher support, straight from your device. No third-party grading service, no invented grades. • Subnet Calculator: IPv4 and IPv6 math: CIDR, network, broadcast, host ranges and equal splits, with a live bit view and RFC-correct /31 and /32. • IP Converter: turn any IP notation into every other form, and see how an IPv4 address rides inside IPv6. • MAC Converter: every MAC address notation, EUI-64, link-local, and a fully offline vendor lookup. Randomized phone MACs are flagged as randomized, never given a fake vendor. • Network Details: your Wi-Fi name and access point vendor, local and public IP address with its network owner, router address, DNS servers, your real cellular radio (5G, or 5G riding a 4G core) and NAT64 detection. ACCESSIBILITY Every screen is tested by hand with VoiceOver. Result rows read as one sentence, every long-press action is also a rotor action, and the ping chart supports Apple's Audio Graphs, so you can hear your connection as rising and falling tones. Larger Text, Reduce Motion and Voice Control are supported. One honest limit: I have no Braille display, so Braille output is untested. PRIVATE BY DESIGN Radien uses Apple frameworks only: no third-party SDKs, no analytics, no data collection. The MAC vendor and network owner tables are bundled on the device, and certificates are read locally, never sent to a checking service. Your network is your business. RADIEN PRO Radien is free to use, with a one-time Radien Pro unlock for the power features: Radien Checkup, Multi Ping, more Wake on LAN devices with groups, widgets and the Control Center control, custom DNS resolvers and extra record types, advanced port presets, full TLS depth, device makers and names, MAC vendor lookup, network names, alternate app icons, tuning options and sharing. Buy once, keep forever. No subscription. Built by an independent developer. Feedback is welcome and read personally.

Verdict
The clearest difference is in-app purchases: TGSpeechBox at none against Radien's 1. TGSpeechBox also leads on iOS requirement (16.0 vs 18.0). Radien's advantage is update cadence (every 4 days vs weekly). On price, ads and device support there is nothing between them.
